Plastic extruder control system including the heating system, cooling system and processing parameters measurement system, is mainly composed of electrical appliances, instruments and actuators (i.e., control panel and work station). Its main role is: control and adjustment of the main auxiliary motor drag, output to meet the requirements of the process speed and power, and can make the main auxiliary coordination work; Testing and adjusting squeeze molding machine, plastic temperature, pressure, flow rate; Implementation of the whole unit control or automatic control.
Extrusion unit electrical control is roughly divided into transmission control and temperature control of two parts, realize the extrusion process including temperature, pressure, screw revolution, cooling, machine barrel screw cooling, cooling products, and outside diameter control, speed and traction, neat row line and ensure the line plate from the line in empty plate to a plateful of constant tension control.
1. The temperature control of the extrusion molding machine host
2. Squeeze molding machine pressure control
3. The screw rotation speed control
4. Outer diameter of the control
5. Winding tension control
6. Electrical automation control of the machine
